    Default Evaporation

    I would like to find out how much water i am losing due to evaporation. I know there are alot of factors like surface area,humidity,temp ect. i did a search to find some type of calculation to figure out what the loss should be but came up empty. Does anyone know how to figure this out?
    It may also help with checking for leaks,small cracks and the like. Thanks for any help

    I remember reading something on here about evaporation but it may have been from before the crash because i could not find it.

    It is nearly impossible to accurately calculate the water loss. It is dependent on water temp, air temp and wind. However, it does not seem to be dependent on surface area.

    Have you tired the bucket test? Place a bucket on the first step of the pool and fill to the same water level as the pool. If the pool drops faster than the bucket, you have have a leak somewhere.

    Good luck

    I agree with the other posts: This is beyond what you can do manually. Maybe if you had a computer with a weather station and sensors to check pool temperature and sunlight intensity, you might be able to write software to simulate the evaporation. Much too complex a calculation by hand, as it can change from one second to the next.
